Abstract
The invention relates to an adjustable voltage divider arrangement produced by hybrid technology, having a first current-carrying ohmic resistance layer arranged between two printed conductors and a second resistance layer, which is electrically connected to the first resistance layer and to which there is connected a third printed conductor as a pick-off electrode. A cut is made in the second resistance layer for adjusting the voltage divider so that a desired level can be picked off at the pick-off electrode. To be able to pick off very low divider voltages with the required accuracy with only a slight increase in region required by the voltage divider arrangement, it is proposed that the second resistance layer be connected to the first resistance layer over printed conductors in such a way that a first divider voltage tapped at the first resistance layer is applied to the second resistance layer, and a partial voltage of the first divider voltage can be picked off at the pick-off electrode connected to the second resistance layer.
